1. Automated Model Versioning with GitHub Repositories


    To implement automated model versioning with GitHub repositories using Pulumi in Python, you'll need to set up a GitHub repository and automate the process of committing changes to your models. You can accomplish this by utilizing GitHub Actions or other CI/CD tools to trigger operations whenever changes to your models are detected.

    Here is a step-by-step guide, followed by a Pulumi program that sets up a GitHub repository configured to handle automated model versioning.

    Step-by-Step Guide:

    1. Setup a new GitHub repository: This repository will be used to store and track versions of your models.
    2. Implement an automation script/tool: Write scripts that use GitHub's API to commit and push model changes. For continuous integration and version control, GitHub Actions can also be used to automate these tasks.
    3. Commit and push models: Every time you have a new version of your model, your automation tool will commit the model with a proper version tag and push this to your repository.
    4. Track versions: Utilize GitHub's release feature to create new releases each time you push a new version of your model.

    Pulumi Program:

    The following Pulumi program in Python sets up a new GitHub repository with some configurations useful for model versioning:

    import pulumi import pulumi_github as github # The name of our repository repo_name = "model-versioning-repo" # Create a new GitHub repository to store the model versions repo = github.Repository(repo_name, description="Repository for automated model versioning", visibility="public", # This repository will be public, change to 'private' if needed auto_init=True, # Automatically initialize the repository with an initial commit ) # Optionally, you can set up GitHub Actions here to automate the versioning process # For the simple setup, we stick to repository creation only # Export the URL of the created repository pulumi.export('repository_url', repo.html_url)

    This code does the following:

    • Imports the required Pulumi and Pulumi GitHub modules.
    • Defines the repository name (repo_name) that will be used for model versioning.
    • Creates a GitHub repository using github.Repository.
      • The name of the repository is passed as repo_name.
      • A description is provided for clarity.
      • The visibility is set to 'public', but you can set it to 'private' if you prefer.
      • The repository is automatically initialized with an initial commit by setting auto_init to True.
    • The URL of the created repository is exported as an output.

    To use this Pulumi program, ensure you have Pulumi and the required GitHub access token configured on your system. Save the above code to a file named __main__.py, and run pulumi up to create the infrastructure.

    Remember, this setup does not include the actual implementation of versioning your models, which would typically be done through GitHub Actions or other scripts using GitHub API to push updates to your repository. You may also consider setting up branch protection rules, webhooks, and other repository settings depending on your workflow.
